电子商务网站建设需要哪些步骤聚成网站建设

背景

最近在做一个权限可见的功能。每一个订单都有创建人和创建人部门，而查询订单时可以查看自己的或者自己可见部门的。
比如你可以看电商组下的订单，那么自然可以看到电商A组下的订单。

使用ES写一个demo

搭建ES及数据初始化

docker run -p 9200:9200 -p 9300:9300 --name es-container -e "discovery.type=single-node" docker.elastic.co/elasticsearch/elasticsearch:8.10.3

ES索引的映射

{"order": {"mappings": {"properties": {"createrId": {"type": "keyword"},"department": {"type": "keyword"},"departmentTree": {  "type": "keyword"},"id": {"type": "keyword"},"name": {"type": "text"}}}}
}

其中数据如下

方案1

场景：你可以看电商组（departMentId = 1）下的订单，那么自然可以看到电商A组下（departMentId = 2,3）的订单。

我通过查询你的权限可以获取大部门电商组（departMentId = 1），然后查询大部门的子部门，从而拿到了部门的全集。

代码略，不推荐，因为部门ID多。

方案2

场景：你可以看电商组（departMentId = 1）下的订单，那么自然可以看到电商A组下（departMentId = 2,3）的订单。

但是我在订单上存储的是这个人的部门链，如下图departmentTree
